Acura MDX 2004 Owner's Guide

If you ever have a moderate to
severe side impact, sensors will
detect rapid deceleration and signal
the control unit to instantly inf late
either the driver’s or the passenger’s
side airbag.
Only one airbag will deploy during a
side impact. If the impact is on the
passenger’s side, the passenger’s
side airbag will deploy even if there
is no passenger.The passenger’s side airbag has a
cutof f system designed to turn of f
the passenger’s side airbag if a child’s
head is in the airbag’s deployment
path (see page ).
If a short adult leans sideways, or a
larger adult slouches and leans
sideways into the side airbag
deployment path, the system may
also shut of f the side airbag.
If the side airbag of f indicator comes
on (see page ), have the
passenger sit upright. Once the
passenger is out of the deployment
path of the side airbag, the system
will turn the airbag back on and the
indicator will go out.
There will be some delay between
the moment the passenger moves
into or out of airbag deployment path
and when the indicator comes on or
goes of f .
To get the best protection f rom the
side airbags, front seat occupants
should wear their seat belts and sit
upright and well back in their seats.
A f ront seat passenger should not
use a cushion or other object as a
backrest. It may prevent the cutof f
system f rom working properly.
When you turn the ignition to ON
(II), the indicator should come on
brief ly and go out (see page ). If it
doesn’t come on, stays on, or comes
on while driving without a passenger
in the front seat, have the system
checked.

In a moderate to severe side impact,
sensors will detect rapid deceleration
and signal the control unit to
instantly inflate the side curtain
airbag on the driver’s or the
passenger’s side of the vehicle.If sensors detect the vehicle is
continuing to roll over to the other
side, the control unit will deploy the
other side curtain airbag.Side curtain airbags are designed to
help protect the heads of the driver,
f ront passenger, and passengers in
the outer seating positions of the
second and third rows.
In a rollover toward the passenger’s
side of the vehicle, the side curtain
airbag will inflate even if there are no
occupants on that side of the vehicle. To get the best protection f rom the
side curtain airbags, occupants
should wear their seat belts and sit
upright and well back in their seats.
The SRS indicator light
alerts you to a potential
problem with your f ront airbags, side
airbags, side curtain airbags, or seat
belt tensioners.
When you turn the ignition to ON
(II), this indicator will come on
brief ly then go out. This tells you the
system is working properly.
If the impact is on the passenger’s
side, the passenger’s side curtain
airbag will inflate even if there are no
occupants on that side of the vehicle.
If sensors detect your vehicle is
about to tip over, the control unit will
instantly deploy the side curtain
airbag on the downward side of the
rolling motion.

If the indicator comes on at any
other time, or does not come on at all,
you should have the system checked
by your dealer. For example:If the SRS indicator does not come
on after you turn the ignition to
ON (II).
If the indicator stays on after the
engine starts.
If the indicator comes on or
flashesonandoff whileyoudrive.
If you see any of these indications,
the airbags and the seat belt
tensioners may not work properly
when you need them. This indicator alerts you
that the passenger’s side
airbag has been automatically shut
of f . It does mean there is a
problem with your side airbags.
To reduce the risk of injury f rom an
inf lating side airbag, your vehicle has
an automatic cutoff system for the
passenger’s side airbag.
Although Acura does not encourage
children to ride in f ront, this system
is designed to shut of f the side
airbag if a child leans sideways and
the child’s head is in the side airbag
deployment path.
Objects placed on the f ront
passenger seat can also cause the
side airbag to shut off.

Ignoring the SRS indicator can
result in serious injury or death
if the airbag systems, or
tensioners do not work properly.
Have your vehicle checked by a
dealer as soon as possible if
the SRS indicator alerts you to
a possible problem.

To reduce the chance of airbag-
caused injuries, the system shuts of f
the passenger’s f ront airbag when
the total weight on the f ront
passenger’s seat is about 65 lbs
(30 kg) or less.
If no one is riding in the f ront
passenger’s seat, the airbag will be
automatically shut off, but the
indicator light will not come on.
However, if the light comes on with
no passenger in the f ront, or with an
adult in the seat, there may be a
problem with the advanced airbag
system. Have the vehicle checked by
the dealer as soon as possible.
The Passenger Airbag Of f indicator
may also come on and of f repeatedly
if total weight on the seat is near the
airbag cutof f threshold (65 lbs or 30
kg).
This indicator alerts you that the
passenger’s f ront airbag has been
shut of f . It does not mean there is a
problem with the airbag.
When you turn the ignition switch to
ON (II), the indicator should come

If it doesn’t light, stays on, or comes
on while driving without a passenger
in the front seat, have the system
checked. A f ront seat passenger should not
use a cushion or other object as a
backrest. It may prevent the cutof f

make sure they are operating
properly.
Take your vehicle to an
authorized Acura dealer as soon as
possible. If you ignore this
indication, your airbags may not
operate properly.
Your airbag systems are virtually
maintenance-f ree, and there are no
parts you can saf ely service.
However, you must have your
vehicle serviced if:
Any airbag
that has deployed must be
replaced along with the control
unit and other related parts. If a
f ront airbag inf lates, the seat belt
tensioners must also be replaced.
Do not try to remove or replace
anyairbagbyyourself.Thismust
be done by an Acura dealer or a
knowledgeable body shop.
If this happens, have the passenger
ride properly restrained in a back
seat. If the passenger must ride in
front, move the seat as far to the
rear as possible, have the passenger
sit upright and wear the seat belt
properly.
This indicator may come on and of f
repeatedly if objects are placed on
the front passenger’s seat, or if the
interior temperature of the vehicle
changes suddenly when a door is
opened.

Children depend on adults to protect
them. However, despite their best
intentions many adults do not know
how to properly protect child
passengers. Each year, many children are injured
or killed in vehicle crashes because
they are either unrestrained or not
properly restrained. In f act, vehicle
accidents are the number one cause
of death of children ages 12 and
under.
To reduce the number of child
deaths and injuries, every state and
Canadian province requires that
inf ants and children be properly
restrained when they ride in a
vehicle.
(see pages ).
(see pages ).
If you have children, or if you ever
need to drive with a child in your
vehicle, be sure to read this section.
It begins with important general
guidelines, then presents special

Children who are unrestrained
or improperly restrained can be
seriously injured or killed in a
crash.
Any child too small for a seat
belt should be properly
restrained in a child seat. A
larger child should be properly
restrained with a seat belt and
use a booster if necessary.

With this system, the front
passenger’s airbag is turned of f if
sensors detect a total weight of less
thanabout65lbs(30kg)intheseat.
(See page f or additional
inf ormation about how the f ront
passenger’s advanced airbag works.)
Even if the passenger’s f ront airbag
is turned of f , we strongly
recommend that children age 12 and
under ride properly restrained in a
back seat where they will be saf er.
Front airbags have been designed to
help protect adults in a moderate to
severe f rontal collision. To do this,
the passenger’s f ront airbag is quite
large, and it can inflate with enough
f orce to cause very serious injuries.
To help prevent airbag-caused
injuries to children, this vehicle has
an advanced airbag system.
According to accident statistics,
children of all ages and sizes are
saf er when they are restrained in a
back seat. The National Highway
Traffic Safety Administration and
Transport Canada recommend that
all children age 12 and under be
properly restrained in a back seat.
Children who ride in the second or
thirdrowarelesslikelytobeinjured
by striking interior vehicle parts
during a collision or hard braking.
Also, children cannot be injured by
an inf lating airbag when they ride in
the back. 25

Your vehicle has two rows of back
seats where children can be properly
restrained. If you ever have to carry
a group of children, and a child must
ride in f ront:Place the largest child in the f ront
seat, provided the child is large
enough to wear the lap/shoulder
belt properly (see page ).
Move the vehicle seat as far to the
rear as possible (see page ).
Have the child sit upright and well
backintheseat(seepage ).
Make sure the seat belt is properly
positioned and secured (see page ). Many parents say they pref er to put
an inf ant or small child in the f ront
passenger seat so they can watch the
child, or because the child requires
attention.
Placing a child in the f ront seat
exposes the child to hazards in a
f rontal collision, and paying close
attention to a child distracts the
driver from the important tasks of
driving, placing both of you at risk.
If a child requires close physical
attention or f requent visual contact,
we strongly recommend that another
adult ride with the child in a back
seat. The back seat is far safer for a
child than the front.
If you are not wearing a
seat belt in a crash, you could be
thrown forward and crash the
child against the dashboard or a
seat-back. If you are wearing a
seat belt the child can be torn
from your arms and be seriously
hurt or killed.
During a crash, the belt
could press deep into the child and
cause serious or f atal injuries.
This can prevent children
f rom accidentally f alling out (see
page ).
